For the active immunisation of healthy 18-day-old chicken embryos or healthy day-old chicks against classical or very virulent Infectious Bursal Disease (Gumboro Disease).
There is no need for determination of MDA level prior to vaccination; the delivery vehicle is timing the vaccine virus release individually, according to the maternally-derived antibody level of the chicks.
One full dose is guaranteed to be administered to each chick. There is no risk linked to water administration of usual IBD vaccines.
